Timothy Mason, a faculty member at Université de Paris 8, has written prolifically, and much of this writing is generously available on his web site. A part that I particularly enjoy is some extensive information on language acquisition that comes from some previous lectures.
His Could Chomsky be Wrong? is an interesting mix of multiple links, synopses of others writings, and Mason’s well thought out arguments. For anyone wanting this often ignored side of the story this is a great place to go. I particularly enjoyed Geoffrey Sampson’s linked There is no Language Instinct, which can be found on his site.
